Google Sheets Conditional Formatting Multiple parameters

I have a unique Conditional formatting situation.

Columns E-H have check boxes as well as K-L
Columns I-J require various text in cell

With this:

=and($E3, $F3, $G3, $H3, $K3, $L3)

I can format the checkboxes if checked, but how do I incorporate if $I3 and $J3 have text into this formula?

Thanks in advance

>Solution :

Can you try this out:

=and($E3, $F3, $G3, $H3, $K3, $L3, ISTEXT($I3), ISTEXT($J3))
